For comprehending the duties of fashion designer, Sharon(1989) has suggested to look at the procedure how the goods are being produced. The purpose of this research is to identify the task of domestic fashion designer by comparing and analyzing one's work range and performing level in the fashion merchandising process according to the brand types which one is involved in. The preliminary research for the questionnaire was conducted with 5 chief designers of woman's apparel manufactures in Seoul. They were asked to judge if designer's tasks fit to their carry-out operations in the pre-fixed questionnaire which had been done based on preliminary researches and literatures related with fashion merchandising process. The contents of research questionnaire are 11 questions to understand the general characteristics of companies and the participated subjects, and 42 questions to understand the designers' operations. For the selection of NB, among 503 domestic female apparel brands that were in 'Korean Textile Fashion yearbook (2002-2003), the companies that were located in Seoul and possible for cooperation by researcher's personal relationship were selected. For DB, cooperation was requested for brands that were located in Seoul among the 137 brands that participates on Domestic Collection. For GB, 50 stores were selected at random or by personal relationship among 32 GB shops such as Freya Town, Doosan Tower, New Zone, and so on. Total 300 questionnaire distributed to the designers, 192 copies were used for final data analysis. For data analysis, descriptive statistics and ANOVA, Sceffe test were used using SPSS V. 11 1. The participated fashion designers operated 41 categories of suggested 42 categories in the fashion merchandising process. 2. The ranges and contents of tasks in the fashion merchandising process that fashion designers mainly carry-out are very different according to the brand types and showed much different level of task carry-out. Only in the categories of 'fashion trend information' and 'design ideation', all three brand type showed the highest level of task performance. And the design related tasks presented common higher level of performance than the other tasks in all brand types. In order to comprehend the operation of fashion designer, various approaching methods are required according to various apparel manufactures' characteristics.

Most Websites perform login process for authentication. But simple features like ID and Password have no trust because most people worry about appropriation. So the youth can easily access illegal media sites using other's ID and Password. Therefore this paper examine features be adaptable to authentication system, and propose a design of authentication system using multiple features. A proposed authentication system has two categories, such as low-level and high-level method. Low-level method consists of grant of authentication number through mobile phone from server and certificate from authority. High-level method combines ID/Password and features of fingerprint, character, voice, face recognition systems. For this, this paper surveys six recognition systems such as fingerprint, face, iris, character, vein, voice recognition system. Among these, fingerprint, character, voice, face recognition systems can be easily implemented in personal computer with low cost accessories. Usage of multiple features can improve reliability of authentication.

The purpose of this study is to set the Hallabong tangor's quality standards based on consumer preference survey. Until now the Hallabong tangor's quality standards has been based on the fruit size. Hallabong tangor's quality in agricultural cooperative, citrus agricultural cooperative, and some agricultural corporation has been selected in accordance with its own brand of quality grade using a non-destruction sorting machine. But, setting the Hallabong tangor's quality standards has been based on the convenient and routine method rather than the scientific and objective method, consumer's preference. According to the grade contents, more than sugar $13^{\circ}Bx$ and less than acid 1.10% has been used uniformly. Thus, in this study, based on the consumers' preference of Hallabong tangor, 5-level grades of sugar and 7-level grades of acidity were divided into the total 35-level grades. Based on this, 5-level grades were set and were divided into selling product grades(1~3) and non-selling product grades(4~5).

There have been performed many researched for flood magnitude analysis, for example, the Flood-Duration-Frequency relations in the west. Because flood water stage data are more available rather than flood amount data at flood gauge stations of Korea, this study developed Flood water level-Duration-Frequency (Fwl-D-F) curves using rainfall Intensity-Duration-Frequency(I-D-F) curves for the quantitative flood risk assessment in urban watersheds. Fwl-D-F curve is made from water level data for 18 years at Joongrayng bridge station of Joongrayng River basin in Han River drainage area. Fwl-D-F curve can estimate the occurrence frequency for a certain flood elevation, which can be used for urban flood forecasting. It is expected that the flood elevation can be estimated from the forecasted rainfall data using both Fwl-D-F and I-D-F curves.

Reliability is considered a particularly important design factor for systems that have critical results once a failure occurs in a system, such as trains, airplanes, and passenger ships. The reliability of the system can be improved in several ways, but in a system that requires considerable reliability, the redundancy of parts is efficient in improving the system reliability. In the case of duplicating parts to improve reliability, the kind of parts and the number of duplicating parts should be determined under the system reliability, part costs, and resources. This study examined the redundancy allocation of multi-level systems with serial structures. This paper describes the definition of a multi-system and how to optimize the kind of parts and number of duplications to maximize the system reliability. To optimize the redundancy, the cuckoo search algorithm was applied. The search procedure, the solution representation and the development of the neighborhood solution were proposed to optimize the redundancy allocation of a multi-level system. The results of numerical experiments were compared with the genetic algorithm and cuckoo search algorithm.

This study explored whether the transition to living with a chronic disease changes the level of depression symptoms among middle-aged and older adults in South Korea. We hypothesize that the transition to living with chronic disease leads to a higher level of depressive symptoms. A nationally representative sample (N = 6,284) of adults 45 years and older from the Korean Longitudinal Study of Ageing (KLoSA) was analyzed. Multi-regression modeling was used to examine the association between the diagnosis of chronic disease and the level of depressive symptoms in patients. The findings highlight the need for policy makers, clinicians, as well as patients and their caregivers to become more aware of mental health risks in patients diagnosed with chronic diseases, particularly first-time patients. This study contributes to encouraging greater psychosocial support, including monitoring the level of depressive symptoms of patients who develop chronic conditions and providing appropriate treatments for those at the highest risk.

Many researches have been performed to resist buffer overflow attacks. However, the attack still poses one of the most important issue in system security field. It is because programmers are using library functions containing security hole and once buffer overflow vulnerability has been found, the security patches are distributed after the attacks are widely spreaded. In this paper, we propose a new cache level return address stack architecture for resisting buffer overflow attack. We implemented our hardware onto SimpleScalar simulator and verified its functionality. Our circuit can overcome the various disadvantages of previous works with small overhead.
